SPLICER FOR TROLLEY-CONDUCTORS.

Specification of Letters Patent.

Patented Nov. 2%, 1916..

Application filed August 7, 1911. Serial No. 642,881.

To all whom it may concern.

Be it known that I, lVILLIAM SoHAAKn, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Splicers for Trolley-Conductors, of which the follow ing is a specification.

My invention relates to splicers for trolley conductors, and it has for its object to provide a device of this character which shall be of greater strength and more effective and durable in service than similar devices heretofore employed.

The single figure of the accompanying drawing, which illustrates my invention, is a view, partially in side. elevation and partially in section.

The general outline and structural characteristics of the splicer 1 are Well known in the art the casting 2 of which may be of brass, bronze or other suitable composition and be provided, at each end, with a longitudinal channel 3 having an open bottom and an inclined tubular recess 4 which constitutes a continuation of the channel 3 to receive an end of a trolley conductor, indicated in dotted and broken lines, the end of the trolley conductor to be spliced to that just mentioned bein similarly located at the other end of the casting 2.

The inner end of the recess or passage 4 is enlarged to provide a cylindrical seat 5 terminating in a shoulder 6. A cylindrical sleeve T is fitted closely into the seat 5 and is provided with a tapered inner surface to receive a chuck 8 having correspondingly tapered outer surface and being split longitudinally to grip the trolley conductor when driven into place. The inner surface of the chuck preferably provided with projections or serrations, as indicated, to more securely grip the trolley conductor.

The sleeve 7 is preferably formed of steel. or some alloy or composition of great strength, so as toreceive the pressure exertcdby the chuck and relieve the casing from the strains incident to such pressure, and it is preferably shorter than the seat 5, the material at the outer end of the seat being upset, as indicated at 9, to lock the sleeve in position. The shoulder 6 insures the retention of the sleeve in its proper position in the casing and also receives such strains as may be exerted by the longitudinal pull upon the trolley conductor.

I claim as my invention:

1. A trolley-wire splicer comprising a body member having a wire-holding recess that is open at each end, an integral annular shoulder intermediate the ends of said recess, a sleeve having a tapered inner surface disposed in one end of said recess with one end seated against said shoulder, and a tapered split chuck seated in said sleeve.

2. A trolley-wire splicer comprising a casting having a wire-receiving socket that is open at each end, an'integral annular shoulder intermediate the ends of said socket, an internally tapered steel sleeve disposed in one end of said socket and seated against said shoulder, an upset portion of said casting for locking said sleeve within said socket and a longitudinally split chuck fitted into said sleeve.

8. A trolley-wire splicer comprising a body having a wire-receiving socket open at both ends and provided with an annular shoulder intermediate its ends, an internally tapered sleeve fitted into said socket and having one end in engagement with said shoulder, a longitudinally split chuck fitted into said sleeve and provided with wiregripping projections on its inner surface.

trolley-wire splicer comprising a body member having a longitudinal groove and a connnunicating inclined tubular opening extending through said member for receiving an end of a wire conductor, said member being provided with anannular shoulder intermediate the ends of said opening, a sleeve having a tapered inner surface disposed in the end of said opening removed .from said groove and having its inner end seated against said shoulder, and a tapered split chuck having wire-gripping projections seated in said sleeve.

5. A trolley-wire splicer comprising a body member having a wire-receiving tubular recess therethrough and provided with an integral annular shoulder intermediate the ends of said recess, a sleeve having a tapered inner surface disposed in one end of said recess and having an end thereof seated against said shoulder and a tapered split chuck seated in said sleeve for cooperative engagement with said wire conductor and adapted to grip said conductor when groove and having its inner end seated against said shoulder, said sleeve being provided with a tapered inner surface, and a tapered split chuck provided with wiregripping projections seated in said sleeve and removable therefrom away from said shoulder.

In testimony whereof, I have hereunto subscribed my name this 31st day of July, 1911.

\VILLIAM SCHAAKE.
